In order to avoid the trap receiver and trap exploder from crashing due to flooding of traps, the default values for the QUEUE_LIMIT_MEGS and QUEUE_LIMIT_SECONDS parameters in the trapd.conf file are set to 200 MB and 480 seconds, respectively. On reaching the limits set using these parameters, the sm_trapd queue starts discarding traps. An alert, trapdDiscardingTraps, which is defined in the trap_mgr.conf file is triggered when the queue starts discarding traps. If and when a device is identified as the source of a trap storm, information about it is logged in the sm_trapd log file.

The VMware Smart Assurance Service Assurance Manager Adapter Platform User Guide provides details on the parameters in the trapd.conf file.
